Abstract

The invention discloses a photographing method and device. The photographing method comprises the steps that signal transmission medium information of a current photographing environment is obtained, and transmission speed of ultrasonic wave signals in the current photographing environment is determined according to the signal transmission medium information of the current photographing environment; the distance between a photographed target and a photographing terminal is obtained according to time for transmitting the ultrasonic wave signals of an ultrasonic wave sensor in the photographing terminal, time for receiving ultrasonic wave reflection signals and the transmission speed of the ultrasonic wave signals in the photographing environment; focusing is carried out according to the distance between the photographed target and the photographing terminal. The method solves the problem that in the prior art, as the photographing environment changes, photographing focusing is inaccurate.

Description

technical field [0001] Embodiments of the present invention relate to the field of digital photography, and in particular, to a photographing method and device. Background technique [0002] With the development of shooting technology, more and more intelligent terminals such as tablet computers and mobile phones are equipped with cameras, and people can record the pictures at any time. [0003] The further improvement of people's requirements for the texture of the captured pictures has made the camera functions on mobile terminals more and more powerful, and users have higher and higher requirements for the quality of pictures taken by terminal products. Camera focusing speed, face recognition, automatic capture and other functions All affect the user experience to a great extent. When the scene to be photographed is at a different distance from the camera on the mobile terminal, it is necessary to adjust the focal length, ie focus, to make the scene to be photographed cl...
